Explanatory Note: This table is compiled based on the inherent characteristics of each material, demonstrating that different base polymers have their own most suitable application fields. In actual hot-melt adhesive production, when considering costs, formulation conditions, and processing techniques, developers can adjust the formulation using these existing base materials. By altering the high/low-temperature resistance and polarity of the adhesive, its application fields can be significantly expanded.
